Suppose an investment of 8,200 doubles in value every 7 years. How much is the internet worth after 28 years?
To calculate the value of the investment after 28 years, we need to find out how many times the initial investment doubles in 28 years.
Since the investment doubles every 7 years, after 7 years it will be worth 2 * 8,200 = $16,400.
After 14 years, it will be worth 2 * 16,400 = $32,800.
After 21 years, it will be worth 2 * 32,800 = $65,600.
Finally, after 28 years, the investment will be worth 2 * 65,600 = $131,200.
So, the investment will be worth $131,200 after 28 years.
